I just bought an 02 Mustang GT deluxe coup 4.6. Drove it over 100 miles back home. Needs front struts bad. Hit a bump kinda hard and the windshield wipers would come and wouldn't go off till they got ready. I found a new combination switch in the car and thought this is why this is in here. Went to replace it and the after market alarms went off. So it started to crank in sync with alarm system when the key was in the run position. Long story short I replaced the locking mechanism and completely took out the alarm system witcha was spliced into the wires in the steering column. Still same issue. What do I do?
